Switch loading

[Gary]

Is there a rule of thumb or other mathematical quantifiable measure that
states how much traffic a switch can cope before it bottlenecks? If all
ports say of a 24 port switch are used, will the switch become bogged and
traffic collisions made the flow of traffic and will loss of data be a real
issue to contend with, or will traffic just slow down.

Do you have to keep a certain amount of headroom (i.e. spare ports) on a
switch to prevent the device from overloading?

Cheers

What matters isn't the number of ports or the load on any given number of
ports but the size of the backbone in the switch. For example, the
venerable HP 2524 switch contains a 9.6Gbps switch backbone, whereas the
Cisco Catalyst 3750 switch family provides a 32Gbps backbone.
